Introduction
The Tau 640 camera is a long-wavelength (8 – 14 microns) uncooled microbolometer camera
designed for infrared imaging applications that demand absolute minimum size, weight, and
power consumption. It is available with multiple different lens focal length options, as well as
lens-less (not shown) and narrow-field-of-view (NFOV) options.
The Tau 640 Software Developer’s Kit (SDK) enables camera control using one of several
programming languages including VB6, VB.net, C#, and C++ (MFC). The FLIR Camera
Controller GUI is an example of an application created using the SDK—See “Software Accessory
SDK for Windows & Embedded” on page 2-4.

The camera provides “power-in, video-out” capability, which means that one need only apply input
voltage to receive analog video. For those applications requiring serial control, the Tau 640
camera includes a serial interface (RS-232) for transmitting camera commands and receiving
status. The Tau 640 camera also provides 8-bit and 14-bit digital data options, including CMOS,
BT.656, and the Legacy Photon LVDS—See “Tau 640 Digital Data Channel” on page 4-1.

Software Accessory Alternate Lens Calibration Software
110-0133-72
For customers that furnish their own optics for use with Tau 640 cores, FLIR sells a Windows
application program called Alt Lens Cal. This software enables users to perform a
supplementary calibration of the camera with a lens. This field-calibration process requires the
use of at least one blackbody source (a uniform, controllable temperature reference) that has
an area greater than the diameter of the front of the lens.
The Alt Lens Cal software also requires a customer-furnished PC, which should be dedicated to
this task. The calibration routine calculates gain terms on a per-pixel basis with the customersupplied lens attached to the Tau 640 core, and stores the customer-performed calibration in
non-volatile camera memory. The original factory calibration coefficients are first uploaded from
the camera and stored into a file on the PC, then the new calibration data is downloaded and
stored directly into the camera. Multiple calibration files can be stored on the host computer.
The original factory calibration file can be restored if necessary, and the customer can actually
build a library of lens calibration files for a Tau 640 camera. All OEM customers who add their
own lenses to Tau 640 should use this program for optimal image performance.
Alternately, customers can contact FLIR to purchase a Lens Calibration feature that works with
the FLIR Camera Controller GUI software. Specifically, a DLL can be added to the FLIR Camera
Controller GUI software that provides all the features of the stand-alone Alt Lens Cal software.

The digital data complies with the Base Camera Link standard and should be compatible with
any brand Camera Link Frame Grabber and software.
The FLIR Camera Controller allows you to control the Tau Camera, but does not support
Camera Link frame capture so that a third-party software must be used. FLIR has tested the
ImperX FrameLink Express frame grabber (http://imperx.com/frame-grabbers/framelinkexpress).The ImperX frame grabber comes with FrameLink Express software that allows for
recording single or multiple images (BMP, JPG, TIF, and RAW) as well as standard AVI clips.
Configuration requires selecting 1 TAP, L->R for the tap reconstruction, selecting the
appropriate bit depth that you chose in the FLIR Camera Controller, and clicking “Learn” to
discover the number of digital pixels available.

The Tau 640 camera with a Universal Serial Bus (USB) interface accommodates advanced
camera control through the FLIR Camera Controller GUI. A user also can control the camera
through this interface using their own software and hardware by following the Serial
Communication Protocol and command structure defined in Appendix B. This requires
programming skills and a strong technical background. The FLIR Camera Controller GUI is
offered as a free download from FLIR using a Windows based PC with a standard USB port.
This software provides remote control of various camera features and modes.
The FLIR Camera Controller GUI software is compatible with Windows XP with .Net Framework
version 2.0 or later. The GUI will prompt the user to update to the latest .Net Framework.
Note
We recommend that Windows Update is turned on, keeping the operating system current;
and that you use the latest version of the FLIR Camera Controller GUI
(available on our website).
If your embedded or specialty applications require custom control software, a Software
Developer’s Kit (SDK) is available. Those intending to generate their own custom software are
encouraged to read the remainder of this section regarding the FLIR Camera Controller GUI to
better understand the camera modes and parameters.

Troubleshooting the FLIR Camera Controller GUI
If the FLIR Camera Controller GUI does not link
with the camera, you may see the popup shown at
the right which indicates that the GUI has not
been able to communicate with the Tau 640
camera.
Verify the items in the following checklist:
Is the camera properly cabled to the
host PC?:
Verify that you selected the proper port if it was
not detected automatically. Select Advanced, then
Next> in the Tools→Connection... dialog box. Also,
try disconnecting and then re-connecting the cable
to the PC. If the GUI was launched before the
cable was connected, close the GUI, connect the
cable, then re-launch the GUI.
Is the Baud rate set correctly? Baud
rate must be set in the Tools→Connection...
dialog box. The Tau 640 camera supports Baud
rates of 57600 and 921600.
Is the port already in use by another
application?:
Shut down any other applications that may be
using the port. Also, multiple instances of the FLIR
Camera Controller GUI Program can be
instantiated using different ports so be sure the
camera you are interested in controlling is actually
connected to the physical port.
Is the Tau 640 camera power on?
Verify that the camera is producing an image on a
separate monitor. On cameras with a shutter
installed, at camera power up, you can hear two
sets of a click-click sound, separated by about 5
seconds, as the shutter performs its on-power-up calibration.
If you cannot initiate serial communication with the camera after verifying these items, refer to
the frequently asked questions (FAQ) at www.flir.com/cvs/cores/faqs/tau/all/
or contact FLIR Customer Support at (805) 964-9797.

Tau 640 User’s Manual
Flat-Field-Correction Mode: Tau 640 includes internal
mechanisms for periodically improving image quality via a
process called flat-field correction (FFC). During FFC, a shutter
briefly blocks the detector array, presenting a uniform
temperature (a flat field) to every detector element. While
imaging the flat field, the camera updates correction
coefficients, resulting in a more uniform array output. The
analog video image is frozen during the entire process, which
takes less than a half second, and resumes automatically
thereafter. Repeating the FFC operation often prevents the
imagery from appearing “grainy”. This is especially important
when the camera temperature is fluctuating, such as immediately after turn-on or when
ambient temperature is drifting. FFC can be controlled manually at any time using the Do FFC
command button.
Tau 640 provides three FFC modes:
Auto: In the Automatic FFC mode, the camera performs FFC whenever its
temperature changes by a specified amount or at the end of a specified period of time
(whichever comes first). When this mode is selected, input windows are available in
the FLIR Camera Controller GUI for specifying the temperature change and the
number of frames that trigger automatic FFC. The temperature change is specified in
degrees, with valid values in the range 0 to 100 in 0.1 degree increments. The time
period is specified in analog video frames (33ms NTSC, 40ms PAL), with valid values
in the range 0 to 30,000 frames. The second set of Auto FCC parameters labeled
Low Gain apply to Tau 640-P cameras with the auto gain switch enabled.
Note
FLIR recommends using the factory default values for the two automatic-FFC parameters if
possible. These values were selected to maintain a high degree of image quality over all
camera operating conditions.
Manual: In Manual FFC mode, the camera does not perform FFC automatically based
on specified values of temperature change or expired time. The FFC will be performed
once upon startup then again using the internal shutter whenever the Do FFC button
is clicked. At camera temperature excursions beyond 0°C and 40 °C, a Do FFC
command is recommended in order to maintain image quality.
External: In External FFC mode a uniform source (blackbody) must be placed in front
of the camera. The image of this uniform source will be subtracted from all
subsequent images. This feature is useful if there are lens or lens mount nonuniformities that are not corrected by an internal FFC. The camera will not perform an
FFC process on startup if the saved state of the camera is External mode FFC.
Many customers have found that the palm of their hand or a table is an adequate
uniform source to perform an External FCC.

3—Basic Operation of the Tau 640 and GUI
The Tau 640 camera displays an onscreen symbol called the Flat Field
Imminent Symbol prior to performing an
automatic FFC operation. As shown in
Figure 3-4, it is the square in the upper
right of the video output and is displayed
nominally 2 seconds prior to the FFC
operation. The duration of the FFC
Imminent Symbol can be set using the
FFC Warn Time setting in the Analog
Video tab. Setting the Warn Time to less
than 15 turns off the warning (see
paragraph 3.8).
Figure 3-4: Flat Field Imminent Symbol
External Sync Mode: The Tau
640 camera provides the ability to either accept or output
a frame synchronization signal on pin 21 of the 50-pin
Hirose connector or pin 26 of the Photon Replicator
board. This functionality can also be disabled. The designed
signal levels are 0V and 3.3V.
Disabled: The camera will turn off frame synchronization.
Slave: The camera will accept a frame synchronization signal on the interface
connector. The camera output will be frozen if the camera is in slave mode and no
external synchronization signal is received.
The focal plane array readout cycle starts when the external synchronization signal is
received and the camera will continue the output cycle until the frame is complete.
The frame sync signal embedded in the respective digital output should be used to
acquire digital data, not the external sync I/O.
Maximum external sync input rates are up to 29.980 Hz for NTSC and 27.25 Hz for
PAL. The ‘Slow Video’ versions of the Tau 640 camera will have the same external
sync frame rates, but the image data output will be at 1/4 the rate (NTSC) or 1/3
the rate (PAL).
Master: The camera will output a frame synchronization signal on the interface
connector when configured as a master. The output pulse width will be 100 ns at the
standard frame rates (27.970 Hz for NTSC; 25.000 for PAL).
Operating Mode: The Tau 640 camera will freeze the
analog frame imaged when Frozen is selected. Live video
will cease and the frozen frame will persist. To return the
camera to live video, select Real-Time video mode.
Save Settings: After using the FLIR Camera Controller GUI to change
camera modes and settings to your desired values, use the Save Settings
button to store your current selections as new power-up defaults. The next
time the camera is powered, the Tau 640 camera will remember these saved
settings. If you do not click Save Settings, the changes you make via the FLIR Camera
Controller GUI will be valid only for the current session. Cycling power to the camera will revert
to the previously saved settings.

Image-Orientation Mode: Two Image-Orientation mode selections are provided. Select
one or both to change the orientation of the video image.
Invert: The normal image is flipped
vertically. The pixel on the upper-left
corner of the detector array is displayed
on the lower-left corner of the video
display in Invert mode. Invert is used when
mounting the camera upside-down. Invert
applies to analog, BT.656, CMOS, and LVDS video.
Revert: The normal image is flipped horizontally. The pixel on the upper-right corner of
the detector array is displayed on the upper-left corner of the video display. Revert
mode produces a mirror-image of Normal mode; use for applications where the
camera is imaged through a mirror. Revert applies to analog and BT.656 video only.
Note
Any time the image orientation mode is inverted, a flat-field correction automatically takes
place. Adjusting image orientation should always be followed by a flat-field correction in all
modes.

the Unzoom box checked, the Tau 640
center
camera displays the full sensor array image.
When the Zoom 2x box is checked, a smaller
central region of the sensor array is mapped
to the video output creating the zoom effect.
For NTSC and PAL video formats in 2× zoom
mode, 320 × 240 and 320 × 256 pixels,
respectively, are mapped to the analog video
output. When the Zoom 4x box is checked,
Tilt
160 × 120 (NTSC) and 160 × 128 (PAL)
slider
pixels, respectively, are mapped to the
analog video output. When the Zoom 8x box
Pan
is checked, 80 × 60 (NTSC) and 80 × 64
slider
(PAL) pixels, respectively, are mapped to the
analog video output. This reduced region of
the array is called the zoomed array region.
The BT.656 video output also has the zoom feature, but the CMOS and LVDS do not.
Pan & Zoom, Pan: When in either zoomed mode, you can move the zoomed array region
within the full array area. This digitally simulates panning and tilting. Panning and tilting are
defined as moving the camera image in the horizontal and vertical axes, respectively. The FLIR
Camera Controller GUI Pan and Tilt limits are ±80 × ±60; and ±40 × ±30 when in the Fine
range.
Checking the fine box increases the sensitivity of the slide control so that the zoomed array
moves one half the total range but all step values are achievable. Simple experimentation while
viewing the displayed image will quickly give you familiarity with this feature.

Flat-Field Correction (FFC): The Tau 640
automatically performs flat-field corrections (see paragraph
“Flat-Field-Correction Mode:” on page 3-12). A green square
is displayed on your video monitor as a warning that the FFC
is going to take place. Use this function to set the number of
analog video frames (33ms NTSC, 40ms PAL) during which
the warning will be displayed. The time period, specified in
frames, can range from 0 to 30,000 frames. The factory
setting of 60 frames equates to a two second warning. Setting the FFC Warning to less than
15 turns off the warning.
Dynamic Digital Detail Enhancement (DDE) filter:
The DDE algorithm sets edge enhancement dynamically
proportional to the number of bins occupied in the image
histogram.
In a high dynamic range scene the gain will be higher than in
a low dynamic range scene. This allows faint details to be
visible in high dynamic range scenes without increasing
temporal and fixed pattern noise in low dynamic range
scenes.
The DDE filter operates independently from the AGC and will enhance edges without effecting
brightness or contrast. The valid range of Dynamic DDE setting is from 1 to 63 with 17 being
the neutral setting where the filter has no effect. Settings below 17 will smooth the image
reducing the appearance of sharp edges. Higher DDE settings will enhance all image nonuniformities resulting in a very detailed but grainy picture especially in high dynamic range
scenes. Typical factory settings are between 25 and 30. Settings from 18 to 39 are normal
imaging modes where the edge enhancement can be tuned for the scene. Use the slider to
adjust the setting, or select the text field and type in the desired setting. Avoid using setting 16.
Note
In 14-bit Raw mode, selecting the DDE mode will not affect the digital data output.
Video On/Off: This feature allows you to turn off
the analog video output which will result in some power
savings (approximately 55mW).
Video Standard: Choose the video standard for
your system.

Polarity/LUT: The Tau 640 camera detects and images the
temperatures in a given scene. Within the camera, these temperatures
are mapped (as determined by the AGC algorithm selected) to a range of
0 to 255 values. In a black and white display mode, this range is
converted to shades of grey with, for example, 0 being totally black and
255 being totally white. The 0 to 255 grayshades range sensed is
referenced to a Look-Up Table (LUT) permanently stored in the camera
to convert the scene to a video image. Different LUTs are available to
change the appearance of the displayed image. The most common
selection is either White Hot (hotter objects appear brighter than cooler
objects in the video display) or Black Hot (hotter objects appear darker
than cooler objects). Since the difference between these two modes
simply reverses the choice of darker or lighter for temperature
extremes, this is sometimes referred to as Polarity. Other color LUTs
are available as shown below.
Figure 3-7 shows each of the LUTs as displayed in Test Pattern Ramp Mode starting with the

AGC Modes: The Tau 640 provides five AGC algorithms for Image-Optimization:
Automatic: This is the most sophisticated algorithm
and for most imaging situations, the best all-around
choice. This factory default along with the default
parameter settings should be used in general imaging
situations. In Automatic, image contrast and
brightness are optimized automatically as the scene
varies. This mode provides an AGC which is based on
a histogram-equalization algorithm. Controls for the
ITT Mean (gray scale mid-point), Max Gain (AGC gain)
and Plateau Value are enabled.
The histogram equalization used in the automatic mode scales the 14-bit to 8-bit
transfer function based on the number of pixels in a bin. The more pixels in a bin, the
higher the gain. But the Plateau value is the pixels/bin limit when the transfer function
is maximized. Normally 250 is the plateau value for imaging cameras when more
contrast is desired.
This algorithm analyzes the scene content in real time and redistributes the dynamic
range of the scene. The goal of this redistribution is that every one of the 255 bins of
display dynamic range has an equal number of pixels in it. This method tends to give
better scene contrast under conditions where the scene statistics are bimodal (for
example, a hot object imaged in a cold background. It should be noted that the heat
range in a given scene is not divided evenly across the grey levels sent to be displayed.
Instead, the AGC algorithm analyzes the scene and distributes the dynamic range to
best preserve statistical scene content (populated regions of the histogram) and
display a redistributed scene representation.
Once Bright: In this mode, the brightness will be set once when the mode is selected.
The brightness (level) is calculated as the mean of the current scene when the Once
Bright button is selected. The scene is mapped to the analog video using a linear
transfer function. Image contrast can be adjusted by the Contrast slider. This is the
only user adjustable parameter. Upon entry into the once bright mode, the currentlystored value of contrast is applied (i.e. the power-on defaults or the last saved values).
Auto-Bright: In this mode, the brightness (level) is calculated as the mean of the
current scene just as in Once Bright mode. The difference with Auto-Bright is that
the values selected for the start and end of the linear transfer function are
automatically updated in real-time, not only at the start of AGC mode selection. The
Brightness Bias offsets the displayed image in intensity. Upon entry into the auto
bright mode, the currently-stored values of Contrast and Brightness Bias are applied
(i.e. the power-on defaults or the last saved values).
Manual: In this mode, image Contrast (gain) and Brightness (level) are entered
completely manually via the sliders. The scene is mapped using a linear transfer
function. Upon entry into the manual mode, currently-stored values of brightness and
contrast are applied (i.e. the power-on defaults or the last saved values).

Linear Histogram: Image contrast and brightness (gain and level) optimized
automatically based upon scene statistics using a linear transfer function. Controls for
the ITT Mean (sets grey scale midpoint) and Max Gain (AGC gain) are adjustable by
entering the value in the Automatic Parameters section. The Linear Histogram
algorithm uses scene statistics to set a global gain and offset (contrast and
brightness) for the image. Upon entry into the linear histogram mode, the currentlystored values are applied (i.e. the power-on defaults or the last saved values).
Note
In Manual mode and Once Bright mode, the brightness setting must be updated as the
camera temperature changes. To avoid this issue, it is recommended to use Automatic or
Auto Bright right modes when possible. Also, AGC mode will only affect the digital data output
if the Digital Video output mode is set to 8-bit data. The 14-bit digital data bypasses the AGC
sections of digital processing.
Linear Parameters: Used for fine tuning the Auto Bright, Once
Bright, and Manual modes, these settings are contextually active
depending on which Algorithm is selected. Each of their settings is
described above.
Once Bright – Only the Contrast control is active.
Auto Bright – The Brightness Bias and Contrast controls
are active.
Manual – The Brightness and Contrast controls are active.
Automatic Parameters: Used for fine tuning the
Automatic and Linear Histogram modes, these settings are
contextually active depending on which AGC algorithm is
selected. Each of their settings is described above as they
pertain to the particular Algorithm.
Automatic – The Plateau Value, ITT Mean, and Max
Gain controls are active.
Manual – The ITT Mean and Max Gain controls are
active.

pixels located 20 pixels to the left and 10 pixels down
from the center of the FPA.
The new AGC ROI size setting is not active until the Set
button is pressed.
The AGC ROI may be set independently for Unzoom,
Zoom 2×, Zoom 4×, and Zoom 8×. The AGC ROI may be set anywhere in the full array size, even
outside the zoom window. The Pan and Tilt function will attempt to move the Zoom AGC ROI to
remain centered on the zoom window. If the camera is being used in zoom mode, it is
recommended that the zoom AGC ROI be set to the same size as the zoom window.

Tau 640 Digital Data Channel
The Tau 640 camera provides three digital data channels which can be configured through
software from the generic pinout definitions shown in Table 5-2 on page 5-2. The BT.656
channel output is a digitally encoded analog format which contains image, symbol, and color
information. The CMOS channel is a parallel image data output. The Legacy LVDS channel is
common with the FLIR Photon camera. Designers and integrators should provide electrostatic
discharge (ESD) and over voltage protection for Tau 640 cameras using digital data channels
because the digital signals on the 50-pin Hirose connector are routed directly to the FPGA.
4.1
XP Bus Setting—BT.656 Digital Interface
The BT.656 parallel output is a common interface which will drive many LCD displays. The data
is digitally encoded NTSC/PAL video and will have AGC, DDE, symbols, and color included. The
signal levels are 0 - 3.3 V CMOS logic and are intended to drive boards mounted directly to the
Tau 640 camera. The BT.656 output is not intended to drive a cable. Table 4-1 shows the
connector pin definitions with BT.656 enabled. Also shown in the table are the optional discrete
input pins. Figure 4-1 details BT.656 format and timing. The horizontal pixels are interpolated
such that every eighth pixel is replicated (640 x 9/8 = 720) to produce the 720 pixels per line
required by the format.

Detail
Note 1
This function is a backward compatible function with Photon. The voltage level of this pin controls the LUT
applied to the analog image. The pin has a pull-up so that the no-connection state is High (3.3 V). When this
pin is high (3.3 V), the analog image will use the White Hot pallet (LUT 1 in the standard LUT file). When this
pin is low (0 V), the analog image will use the Black Hot pallet (LUT 2 in the standard LUT file). The camera
will power up in the saved default state and switch to the discrete input defined state when the pin state is
changed.
Note 2
This function is a backward compatible function with Photon. The voltage level of this pin controls the zoom
state of the analog image. The pin has a pull-up so that the no-connection state is High (3.3 V). When this pin
is high (3.3 V) the analog image will be in the 1x zoom state. When this pin is low (0 V) the analog image will
be in the 2x zoom state. The camera will power up in the saved default state and switch to the discrete input
defined state when the pin state is changed.
Note 3
This function is required for effective use of Shutterless Tau 640 cameras. The application of positive going
edge to this pin shall perform the Do FFC function (0x12 command).
Note 4
This pin is normally at 0 V and changes to 3.3 V when the FFC imminent icon is present on the analog display.
The FFC_Warn_Time command (0x3C) controls both the analog icon and this pin.
Note 5
This function is required to enable additional user control of the camera. The default state is Automatic mode
with the input at 3.3 V held by an internal pull-up. When the signal is pulled to zero volts the camera will
switch into Manual mode. The FFC_Mode_Select (0x11 0=manual, 1=automatic) command has equal
precedence with the discrete pin and the camera will be in the last state set by either the discrete or serial
command. The camera will power up in the saved default state and switch to the discrete input defined state
when the pin state is changed.
Note 6
This function will change the color LUT from the current value to the next LUT in the table when the Discrete
pin transitions from the floating state to the ground state. No LUT change happens on the transition from
ground to float. The LUT state after LUT14 will be LUT1.
Note 7
This function will change the current zoom state from Unzoomed to 2x to 4x to 8x zoom whenever the
discrete pin changes from the float state to the ground state. The Video_Mode command (0x0F) has equal
precedence with this command.
Note 8
Not defined. Connection of either 3.3 V or 0 V to this pin will have no effect on camera operation.

Camera Link Interface
The Tau Camera Link accessory board can be used to capture digital data from the Tau
camera. The Tau Camera Link accessory board has four connectors.
• The Camera Link accessory board has the mate to the 80-pin Hirose connector on
the Tau core. Power and communication are supplied to the core from the Camera
Link accessory. The core receives analog video and CMOS digital data from the
core.
• The mini-USB connector receives power and communication from a host though the
USB cable. The Camera Link accessory converts USB protocol to high speed serial
format for the Tau core.
• The MCX coaxial connection provides access to the camera analog video output
(NTSC or PAL)
• The 26-position Mini-D-Ribbon (MDR) Camera link connector provides the output
interface for camera digital data. This connector does not support power over
Camera link. This connector does not support serial communication over Camera
Link.
This accessory conforms to the Camera Link standard as Base Configuration type 14-bit x 1.
The Tau CMOS data interface has a Frame sync, Line sync, Data bus, and a pixel clock which
runs at 10.5MHz (see section 4.X). To be compliant with the transmission standard the Tau
Camera Link accessory up samples data to achieve minimum data rate. The Camera link data
clock is running at 21MHz. Data is double sampled so that the output is equivalent to: Pixel1,
Pixel1, Pixel2, Pixel2, Pixel3, Pixel3, …, Pixel638, Pixel 638, Pixel639, Pixel639 in each row.
The Frame Valid clock it true during valid lines of data. The Line valid clock is true during valid
pixels in each line. The Data Valid clock is true for every other pixel. It is important that the
Camera Link receiver device uses all three control clocks (some inexpensive models ignore Data
Valid).
In order to use a Camera Link Module for acquisition of data, you will need to first enable the
CMOS XP Bus Output using the FLIR Camera Controller. This option is found under Video =>
Digital Video. On this same page, you can select either 8-bit or 14-bit digital output. Once you
make these changes, it is a good idea to save settings to make them power cycle consistent.
You can do this after clicking Setup.
The digital data complies with Base Camera Link standards and should be compatible with any
brand Camera Link Frame Grabber and software. FLIR has tested the ImperX FrameLink
Express frame grabber (http://imperx.com/frame-grabbers/framelink-express).
The FLIR Camera Controller allows for control of the Tau Camera, but does not support Camera
Link frame capture and third-party software must be used. The ImperX frame grabber comes
FrameLink Express software that allows for recording single or multiple images (BMP, JPG, TIF,
and RAW) as well as standard AVI clips. Configuration requires selecting 1 TAP, L->R for the tap
reconstruction, selecting the appropriate bit depth that you chose in the FLIR Camera
Controller, and clicking “Learn” to discover the number of digital pixels available.

4—Tau 640 Digital Data Channel
Photon Camera Legacy LVDS Output
The Tau 640 camera provides a digital data channel that outputs camera data in a digital
format compatible with FLIR Photon camera tools and accessories. This channel can be used in
conjunction with commercially-available digital frame grabbers, digital displays, or custom
electronics. For Tau 640 users with applications that require custom control software, a
Software Developer’s Kit (SDK) is available to support your development. The SDK accessory is
described in the Accessories portion of this User’s Manual. Using the Digital Data Channel is an
advanced regime that should only be attempted by qualified customers.
The digital data channel can be configured to output 14-bit data after application of calibration
(Non Uniformity Correction or NUC) terms. This mode is most useful for external signalprocessing and/or analysis of the camera output. The digital channel can also be configured to
provide 8-bit data after application of video processing algorithms—Automatic AGC mode,
white-hot/black-hot polarity, image orientation (Invert, but not Revert), and DDE filtered. The 8bit data is essentially a digital version of the video stream provided on the analog video channel
and is therefore more appropriate than the 14-bit data for interfacing to a digital display.
The digital data channel employs serial low-voltage differential signaling (LVDS). The channel
consists of three signal lines—a clock, a composite sync (frame sync and data valid), and serial
data. This is a modern high speed interface employing a twisted pair current loop architecture.
National Semiconductor offers a good introduction and overview in the following document:
http://www.national.com/appinfo/lvds/files/lvds_ch1.pdf.
A serial-in-parallel-out (SIPO) module is available from FLIR for converting the serial data to 14bit parallel LVDS output (plus frame sync, line sync, and pixel clock). The parallel data can be
captured using a frame-grabber board installed in a PC.
One frame grabber possibility is the National Instruments IMAQ PCI-1422 board using digital
interface cable part number 308-0013-00. Another frame grabber option is the Bit Flow
RoadRunner Model 14-M board using digital interface cable part number 308-0016-00-03.
Both of these computer-based frame grabber boards require third-party software not offered
or supported by FLIR.
FLIR supplies camera setup files for both the IMAQ and Bit Flow frame grabber boards, but
FLIR does not formally support their use, nor do we claim or guarantee that these setup files
will be suitable for any particular use or application.

4—Tau 640 Digital Data Channel
4.5.2 Legacy LVDS Digital Data Channels
The camera provides two digital ports.
• Port 1 consists of the signals SD_CLK+, SD_FSYNC+, and SD_DATA1+, SD_DATA2.
• Port 2 consists of the signals LVDS_VID1+, and LVDS_VID2+.
Note
14-bit and 8-bit timing and format are identical except only 8 bits (LSBs) are available in 8-bit
mode.
Port 2 is currently undefined—do not connect to these signals
All signals in the digital data interface employ low-voltage differential signaling (LVDS).
The clock rate of DATA_CLK+ is 73.636 MHz.
The timing of the digital data interface is shown in Figure 4-4 and Figure 4-6.
Note
The LVDS Data_Out transitions on the rising edge of DATA_CLK+ and there is no delay.
Data should be sampled on the falling edge of DATA_CLK+.
The format of the digital output shall be is in Figure 4-5.

Overview of the Electrical Interface
Input Power
The Tau 640 camera operates from DC power per the specifications given below. It is common
in simple operational scenarios to use an inexpensive wall-powered adapter. The Tau VPC
module makes this easy by providing a USB connection.
The camera operating in a steady-state condition consumes around 1W of power. During
startup there is an inrush current of up to 1 A (at 5 V) for 1 ms. Cameras equipped with the
compact shutter will draw 2.75 W (550 mA at 5 V) for 200 ms during the flat-field operation
which occurs during startup and periodically thereafter. Typical start-up times are 3 to 4
seconds.
Caution!
Reversing the polarity of the input power will damage the camera’s internal power supply.
This damage will not be covered under the camera warranty.

The Tau 640 camera has been tested and found to meet radiated emissions specifications of
FCC CFR Title 47 Part 15 Subpart B, and EN 61000-6-3 (CISPR-22 limits equivalent to Class
B) when properly shielded and grounded. The less stringent Class A requirements are met with
the back cover on. It is the responsibility of the systems integrator to verify EMI/EMC
compliance at the system level.
5.2
Hirose 50-Pin Connector
In the Tau 640 camera’s simplest form (no accessories attached), one connector provides the
electrical interface. This connector is a 50-pin Hirose board-to-board style connector, per
Hirose Part Number: DF12-50DS-0.5V(86). Hirose offers a variety of mating connectors
including their SFM(L), SMT, and SFSD style products. Designers and integrators should
provide electrostatic discharge (ESD) and over voltage protection for Tau 640 cameras using
digital data channels because the digital signals on the 50-pin Hirose connector are routed
directly to the FPGA. The primary Tau 640 connector is shown in Figure 5-1.

5—Overview of the Electrical Interface
Analog Video Output
The Tau 640 camera can be configured to provide either NTSC or PAL analog video output.
These analog output standards allow direct video connection to common video display or
recording devices such as TV monitors and VCRs. Typically, an analog monitor input signal is
provided over a coaxial cable and uses either an RCA (consumer based electronics) or BNC
(generally associated with professional or scientific equipment) style connector.
When the VIDEO_LO signal is tied to ground, the analog video signal meets the timing and
voltage requirements of either NTSC or PAL protocol. (The FLIR Camera Controller GUI
software allows you to select between NTSC or PAL video output formats. The NTSC analog
video format is the default in all cameras.)
If you are creating a custom cable to carry the analog video signal from the Tau 640 camera to
your monitoring or recording device, you should use 75 Ohm characteristic impedance coaxial
cable and terminate into a 75 Ohm monitor. These specifications represent standard video
cabling and I/O and will likely be the default for any generic video receiving hardware you
purchase. Per the pin function table, you will use the VIDEO_LO and VIDEO_HI pins for the
analog video output signal. Specific video characteristics are given in the table below.

Command and Control Channel
Remote control of the Tau 640 camera is provided via a RS-232 serial interface consisting of
signals named RX, TX and GND using 3.3 volt signal levels. Chapter 3 provides information
regarding remote control using the FLIR Camera Controller GUI. Appendix B describes the
serial communications protocol in detail for the Tau 640 camera.
5.5
LVDS Digital Data Channel
The Tau 640 camera provides real-time serialized digital video. The camera outputs either 8-bit
or 14-bit data using the SD_CLK±, SD_FSYNC± and SD_DATA± signals. Conversion of the serial
data to a parallel format for data acquisition requires a serial-to-parallel converter accessory.
Information regarding the digital data interface is provided in Chapter 4.
5.6
Parallel Digital Data Channel
The Tau 640 camera provides a digital parallel channel with real-time parallel digital video. The
XP-Bus may be configured for either CMOS or BT.656 format. Information regarding the digital
data interface is provided in Chapter 4.

Appendix B Serial Communication Technical Details
B.1
Serial Communications Primary Interface
The camera is capable of being controlled remotely through an asynchronous serial interface
consisting of the signals named RX, TX, and GND using 3.3 volt signal levels.
Note
The camera is compatible with most RS232 drivers/receivers but does not implement
signaling levels compliant with the RS232 standard voltage levels.
B.2
Serial Communications Protocol
• The required serial port settings are shown in Table B-1.
• The camera does not generate an outgoing message except in reply to an incoming
message.
• The camera generates an outgoing reply to each incoming message.
• All messages, both incoming and outgoing, adhere to the packet protocol defined in
Table B-2 and the subparagraphs that follow. The first byte i.e., the Process byte is
transmitted first followed by the rest of the bytes in the order specified.
• All multi-byte arguments defined herein uses big-endian ordering (MSB first).
• The serial inter-byte timeout is factory set to 100ms
• Only use the function commands listed in Table B-4. Unsupported commands may
corrupt the camera's software.
• For reference only, a sample command and response is shown in Table B-5.

Baud rate:
57600
Data bits:

Example Process Code
Transmission is LSB first (for each byte) and most significant byte first on multi-byte
messages. All bytes are preceded by a zero start bit and followed by a one stop bit.
The camera core is designed to talk to a PC serial port directly and may seem inverted
if direct communication to a logic device is desired.
6E = 0 0111 0110 1 = Start bit, E with LSB first, 6 with LSB first, Stop bit
On an oscilloscope the observation is, Idle low but, zero high. Starting at idle, when the
signal goes high, that is the first 0; then two 0’s high, three 1’s low, one 0 high, two 1’s
low, one 0 high, one 1 low, (6E complete).

Appendix B—Serial Communication Technical Details
B.4.1 Byte Count Bytes
• On all incoming and outgoing messages, the Byte-Count Bytes are used to specify
the total number of data bytes in the packet.
Note
The number of data bytes in the packet is not equal to the total number of bytes in the
packet. For example, a No-Op serial command contains zero data bytes.)
• The Byte Count must be an even number from 0 to 0x1F4 (500 decimal).
B.4.2 CRC Bytes
• On all incoming and outgoing messages, two cyclical redundancy checks (CRCs) are
calculated using CCITT-16 initialized to 0.
• CRC1 is calculated using only the first 6 bytes of the packet.
• CRC2 is calculated using all previous bytes in the packet (i.e. bytes 0 through N).
B.5
Example of the format of a serial message
Table B-5 describes the bytes that are transferred when the FFC_MODE_SELECT (0x0B)
command is issued to the camera to set the mode to Auto (0x01) and to get the FFC mode:

Tau 640 User’s Manual
Description of Serial Commands
B.6.1 Camera Defaults
The RESET_FACTORY_DEFAULTS command sets the current settings to the factory default
values. In order to save these values as power up defaults, it is necessary to do a
SET_DEFAULTS command.
B.6.2 AGC algorithms
Use the AGC_TYPE command to select one of the following AGC algorithms:
• Automatic
• Once Bright
• Auto Bright
• Manual
• Linear
B.6.3 Pan and Tilt
The PAN_AND_TILT command controls this feature in the camera when the image is zoomed. It
does not have any effect when the image is not zoomed. The center of the screen is considered
as coordinate (0,0).
A positive number is needed to pan right and negative number to pan left. A pan value of 1
pans to the right by one column and a pan value of -1 pans to the left by one column from the
center of the image.
A positive number is needed to tilt downwards and a negative number to tilt upwards. A tilt
value of 1 tilts downwards by one row and a tilt value of -1 tilts upwards by one row from the
center of the image.
When the image is being panned or tilted the ROI moves along with these coordinates. The
limits for the zoom ROI have been set to one and a half times the number of rows and columns
in the video. This is to enable a user to pan and tilt the zoomed portion of the image without any
change in the AGC if the image being looked at does not change. This also means that the AGC
of the image is also determined by portions of the image that is not being currently viewed.
B.6.4 DDE filter
The commands to control the DDE filter settings are DDE_GAIN to control the gain,
DDE_THRESHOLD to control the DDE filter threshold, and SPATIAL_THRESHOLD to control the
spatial threshold of the DDE filter. The image remains unchanged when the value of the DDE
gain is 0 and 17. The image becomes unfocused/unsharpened when the value is between 1
and 15. The image becomes more sharpened when the value is above 17. Increasing the DDE
threshold will make the edges sharper. For threshold values between 0 and about 50 the effect
on the image is lesser and has a greater effect above approximately 50. Increasing the spatial
threshold value will make the image look smoother.
B-12
October 2010
TAU-0640-00-10, version 100
Tau 640 User’s Manual
Appendix B—Serial Communication Technical Details
The DDE filter has an automatic mode that when activated controls the DDE Gain using a
combination of the Dynamic DDE setting and the scene dynamic range. The valid range of the
Dynamic DDE setting is from 1 to 63. Dynamic DDE settings between 1 and 16, provide image
smoothing, with a setting of 1 providing the most smoothing. A Dynamic DDE setting of 17
turns off the Dynamic DDE. A Dynamic DDE setting between 18 and 39 sets the imaging mode
DDE Gain between 16 and 40. A Dynamic DDE setting of 40 or greater provides maximum
enhancement but image artifacts may also be enhanced giving an image with some fixed
pattern noise.
B.6.5 Spare Serial Communications Channel
The camera provides a spare serial communications port consisting of the signals: RX2, TX2,
and GND.
Note
This serial communications channel is intended for communication with RS-232 controllable
systems.
B.6.6 Digital data
The DIGITAL_OUTPUT_MODE command allows the users to select one of the following digital
data options
• 14-bit data
• 8-bit data
• digital off
• 14-bit unfiltered
• 8-bit inverted
• 14-bit inverted
• 14- bit inverted unfiltered
• XP-channel setting

C.1
Operation of the Tau 640 camera using the Photon Accessory Kit
Backward compatibility with existing Photon equipment allows Photon users to connect to the
Tau 640 camera to provide power and obtain video. It also facilitates serial communication for
more advanced camera command and control via the free downloadable FLIR Camera
Controller GUI. In this first section, we will discuss simply applying power and obtaining video.
Using the Accessory Kit’s Interface Cable and I/O Module, plug one end of the Interface Cable
into the mating connector of the Photon Replicator Board on the back of the camera. Connect
the other end of the Interface Cable to the mating connector on the I/O Module labeled
CAMERA.
I/O Module
To video monitor
To Photon
Replicator Board
To power supply
(206-0001-20)
Attach one end of a standard BNC cable to the video port labeled VIDEO on the I/O Module.
Attach the other end to a compatible video monitor’s composite video input. If your monitor has
an RCA input connector, a BNC to RCA adapter can be used.
Plug the power supply into an electrical outlet. Insert the circular plug at the other end of the
power supply into the power jack labeled POWER on the I/O Module and tighten the locking
screw finger tight. The camera will take ~3 seconds to produce an image after you apply power.
You should see an initial splash screen with the FLIR logo displayed, and then live long-wave
infrared video will follow! Point the camera in different directions and notice the imagery. If the
video image appears low in contrast, point the camera at a target with high thermal contrast
such as at a person.

Tau 640 User’s Manual
Remote control of the Tau 640 camera
The Tau 640 camera accommodates advanced camera control through an RS-232 serial
interface. A user can control the camera through this interface using their own software and
hardware by following the Serial Communication Protocol and command structure defined in
Appendix B. This requires programming skills and a strong technical background. The user can
also use the FLIR Camera Controller GUI offered as a free download from FLIR using a
Windows based PC with the standard serial communications and components provided in the
Development Kit. This software provides remote control of various camera features and
modes. The FLIR Camera Controller GUI software is compatible with Windows XP and Windows
7. The PC must have a spare serial communications port or you must use one of the Tau 640
USB accessories (VPC module or Camera Link module). High-speed communication (921600
Baud) is possible using the USB accessories.
Note
A USB to Serial port adapter is acceptable, but the data communication rate must be set to
57600 BAUD.
If your embedded or specialty applications require custom control software, a Software
Developer’s Kit (SDK) is available.
C.3
Connecting the serial communications interface using the
development kit
You should have successfully operated the camera and obtained live video on a monitor as
described in paragraph C.1 “Operation of the Tau 640 camera using the Photon Accessory Kit”
on page C-1.
The only additional hardware required for serial communication is a serial cable connected as
shown below.
To PC serial COM port
(RS232)
To Photon
Replicator Board
Attach one end of a standard RS-232 serial port (9-pin) PC cable to the communications port
labeled RS-232 on the I/O Module. Attach the other end to the serial port on your PC. This
cable should be a standard RS-232 cable, not a cross-over configured serial cable, or nullmodem cable.
